Technical problem to be solved by the invention
As described above, in the keyless entry system, various communication methods are used, and these communication methods have advantages and disadvantages in terms of methods. Therefore, in consideration of user convenience, it is desirable to use an appropriate communication method in a circuit for realizing a keyless entry system, an apparatus equipped with the circuit, or the like (hereinafter, referred to as a locking/unlocking unit) according to a request such as a user's desire or preference. It is desirable that the locking/unlocking by the locking/unlocking unit is familiar to users, and the locking/unlocking can be performed at the same position by the same operation as that in the case of locking/unlocking by a key.
Disclosure of Invention
The present invention has been made in view of the above circumstances, and an object thereof is to provide a locking/unlocking unit which is conventionally familiar to a user and which can lock/unlock a lock at the same position by the same operation as in the case of locking/unlocking with a key.
Means for solving the problems
In order to achieve the above object, a locking/unlocking unit according to the present invention includes: a communication unit that performs communication with the wireless communication terminal for determining whether or not the door of the vehicle can be unlocked or locked; a substrate on which the communication unit is mounted; and a housing that houses the substrate, the housing being housed in a support frame that supports an opening/closing operation portion of the door so as to be operable on an outer side of a vehicle body of the door in a width direction of the vehicle.
According to the above configuration, since the housing is accommodated in the support frame, the communication unit can be disposed in the vicinity of the opening/closing operation unit such as the handle and on the inner side of the opening/closing operation unit in the width direction of the vehicle. Thus, the user can perform the communication for determining whether or not the door of the vehicle can be unlocked or locked between the wireless communication terminal and the communication unit and lock and unlock the vehicle by using the operation and position which have been conventionally used and which are the same as those in the case of performing the locking and unlocking by the key.
In the locking/unlocking unit according to the present invention, the communication unit further includes: a first communication unit that performs wireless communication with the wireless communication terminal by a first communication method; and a first antenna connected to the first communication unit, the substrate including a first substrate on which the first antenna is mounted, the first substrate being disposed outside the case in the width direction and facing the outside in the width direction.
According to the above configuration, the first substrate on which the first antenna is mounted is disposed on the outer side of the case in the width direction of the vehicle, and the first substrate faces the outer side in the width direction. Thus, the first antenna is disposed on the outer side in the width direction of the vehicle and the first substrate faces the outer side in the width direction, and therefore communication is easily performed in the vicinity of the opening/closing operation portion.
In the locking/unlocking unit according to the present invention, the communication unit further includes: a control unit that controls communication for determining whether the door can be unlocked or locked; a second communication unit that performs wireless communication with the wireless communication terminal by a second communication method; and a second antenna connected to the second communication unit, wherein the substrate further includes a second substrate on which the second antenna is mounted, the second substrate is arranged on an imaginary plane intersecting the first substrate, the first communication method is a method of communicating with the wireless communication terminal on which a power storage device is mounted, and the control unit switches the first communication unit and the second communication unit to perform the communication.
As described in the description of the related art, the lock/unlock module (the circuit of the keyless entry system) may be mounted on the door handle or in the vicinity thereof. However, it is not easy to mount the lock/unlock module corresponding to a plurality of communication systems on a small structure such as a door handle. In contrast, according to the above configuration, the substrate is divided into the first substrate on which at least the first antenna is mounted and the second substrate on which other electronic components are mounted, and the substrates and the locking/unlocking unit can be miniaturized by further arranging the substrates in a positional relationship in which the surfaces thereof intersect with each other.
According to the above configuration, the first communication unit can perform wireless communication with the wireless communication terminal by the first communication method using the first antenna, and the second communication unit can perform wireless communication with the wireless communication terminal by the second communication method using the second antenna. The first communication unit and the second communication unit perform communication by a first communication method (hereinafter, referred to as first communication) and communication by a second communication method (hereinafter, referred to as second communication), respectively. In this communication, the control unit can perform communication for switching between the first communication unit and the second communication unit to perform the first communication or the second communication, and can determine whether or not the door of the vehicle (hereinafter, referred to as a vehicle door) can be unlocked or locked.
In the locking/unlocking unit according to the present invention, the second communication method is a method capable of remote communication in comparison with the first communication method.
According to the above configuration, the long-distance communication is performed by the second communication method, and the short-distance communication can be performed by the first communication method or the second communication method. This makes it possible to select an appropriate communication method according to the distance from the vehicle. Particularly in the case of a short distance, an appropriate communication method can be selected according to the characteristics of the communication method. For example, near field communication can select a communication method for performing a near field communication to the extent that the wireless communication terminal covers the first antenna, and long field communication can select a communication method for performing a distance longer than the near field communication.
In the locking/unlocking unit according to the present invention, the first antenna is formed in a ring shape parallel to the first substrate, and the second antenna is mounted on the first substrate and is disposed in an area inside the ring of the first antenna.
According to the above configuration, it is possible to mount both the first antenna and the second antenna on the first substrate, to reduce the size of the locking/unlocking unit, and to reduce interference between the first antenna and the second antenna, thereby making it possible to perform transmission/reception (communication) of electromagnetic waves satisfactorily.
In the lock/unlock module according to the present invention, the second antenna does not overlap with the first board when the first board is viewed in a plan view.
According to the above structure, the second antenna is not shielded by the first substrate. Therefore, the second communication unit can perform the second communication satisfactorily.
In the locking/unlocking unit according to the present invention, the housing may have a fixed portion fixed to the body of the door, and the first antenna may be disposed behind the vehicle with respect to the opening/closing operation portion.
According to the above configuration, the housing can be directly fixed to the vehicle body of the door (the door main body on which the opening/closing operation portion is mounted), and the locking/unlocking unit can be used in combination with the door, so that durability is improved. Further, in a state where the upper lock release member is fixed to the door, since the first antenna is always arranged in the vicinity of the position where the cylinder of the conventional key for unlocking and locking is arranged, such as the rear side, the front side, or the lower side of the vehicle, with respect to the opening/closing operation portion, the user can perform locking and unlocking with the same operation and position as those conventionally used for locking and unlocking with the key. Therefore, the user can feel comfortable.
In the locking/unlocking unit according to the present invention, the housing may have a fixed portion fixed to the door, and the first antenna may be disposed to protrude outward from a vehicle body of the door.
In the lock release assembly, it is necessary to consider the arrangement of an antenna that does not shield electromagnetic waves for wireless communication while being miniaturized. In addition, in the case where the door handle is configured to be movable, it is necessary to take a time until the influence of stress generated in association with the operation is not applied to the unit. Therefore, according to the above configuration, the housing can be directly fixed to the door, and the locking/unlocking unit can be used while being integrated with the door, thereby improving durability. Further, in a state where the upper lock release is fixed to the door, since the first antenna is always disposed so as to protrude outward in the lateral direction of the vehicle from the door, it is possible to realize good communication without shielding electromagnetic waves of the first communication by the vehicle body (metal plate) of the door.
In the locking/unlocking unit according to the present invention, the housing may include a fixed portion fixed to the body of the door, and the first antenna may be disposed on a lower side in a vertical direction with respect to the opening/closing operation portion.
According to the above configuration, the housing can be directly fixed to the body of the door, and the lock/unlock unit can be used in combination with the door, so that durability is improved. Further, in a state where the upper lock release member is fixed to the door, since the first antenna is always disposed in the vicinity of a position where the cylinder of the conventional key is disposed, such as a lower side in the vertical direction of the vehicle, with respect to the opening/closing operation portion, the user can perform the locking/unlocking with the same operation and position as those conventionally used for the locking/unlocking with the key. In addition, since the first antenna is disposed near the user's hand, the user can lock and unlock the lock in an easy posture. Therefore, the user can feel comfortable.
The door handle assembly according to the present invention for achieving the above object is characterized by comprising: the locking and unlocking assembly; an opening/closing operation unit for a door of a vehicle; and a support frame that is disposed inside a vehicle body of the door in a width direction of the vehicle and supports the opening/closing operation portion so as to be operable outside the vehicle body in the width direction of the vehicle, the support frame having a unit holding portion that accommodates the locking/unlocking unit. The width direction of the vehicle is a direction intersecting the front-rear direction and parallel to the ground.
According to the above configuration, the opening/closing operation portion is disposed outside the vehicle body (metal plate) of the door in the width direction of the vehicle, the support frame is disposed inside the main body, and the opening/closing operation portion can be fixed and mounted on the door via the support frame so that the vehicle body is sandwiched between the support frame and the opening/closing operation portion. In this case, the locking/unlocking unit can be mounted on the door in a state of being accommodated in a unit holding portion formed in the support frame. This allows the user to perform locking and unlocking in the vicinity of the operation position, which has been conventionally used and is the same as the case of performing locking and unlocking by inserting a key into the cylinder.

The terminal S includes a terminal antenna 93, a terminal circuit 91 that drives the terminal antenna 93 to transmit electromagnetic waves and receives electromagnetic waves at the terminal antenna 93 to obtain energy and information, a resistor 92, and a capacitor 94, as electronic components or the like constituting a circuit for performing the first communication. At the terminal S, the terminal antenna 93, the capacitor 94, and the terminal circuit 91 are electrically connected in parallel, and the terminal antenna 93 and one end side of the capacitor 94 are electrically connected via the resistor 92.
Hereinafter, the first communication is performed by the NFC communication method, and when the communication system mounted in the terminal S performs the first communication, a case where the electromagnetic wave supplied from the device 100 operates as an energy source will be described as an example. The second communication is performed by Bluetooth (registered trademark), and a case where the communication system mounted in the terminal S can operate with electric power supplied from a secondary battery (not shown) mounted in the terminal S will be described below as an example. Since the NFC communication system and Bluetooth are known communication systems, detailed description of the communication systems and detailed description of circuits for realizing these communications are appropriately omitted. The first communication by the NFC communication method is also performed between card-type terminals (so-called NFC cards) not equipped with a power storage device, and thus locking and unlocking can be performed, but detailed description thereof is omitted.
Locking and unlocking by the assembly 100 is performed as follows. That is, as a result of the communication between the module 100 and the terminal S, when the module 100 acquires ID information (hereinafter, referred to as a permission ID) to which the authority to unlock or lock is given from the terminal S, the ECU determines that the lock/unlock is possible, and transmits a command instructing the lock/unlock to the lock/unlock mechanism. The license ID may be stored in advance in a nonvolatile memory such as an ECU. The locking/unlocking mechanism locks and unlocks the door D in accordance with the command. Further, as long as communication of at least one of the first communication or the second communication is possible, the component 100 transmits an instruction instructing to perform locking and unlocking to the upper lock unlocking mechanism according to a result of the communication. Hereinafter, the instruction for the assembly 100 to transmit the instruction to the lock/unlock mechanism to perform the lock/unlock is simply referred to as a lock/unlock instruction.
(details of locking/unlocking Assembly)
As shown in fig. 1, the module 100 includes a substrate 3 on which a circuit or the like as a communication unit is mounted, and a case 4 in which the substrate 3 is accommodated. The communication unit includes a first circuit 1 (an example of a first communication unit) that performs wireless communication with the terminal S by a short-range wireless communication method, a first antenna 10 (an example of a communication unit, an example of a power supply coil) connected to the first circuit 1, a second circuit 2 (an example of a second communication unit) that performs wireless communication with the terminal S by a long-range wireless communication method, a second antenna 20 connected to the second circuit 2, a processor C, and a storage unit M in which a program for operating the processor C is stored.
The substrate 3 includes at least a first substrate 31 having a flat plate shape on which the first antenna 10 is mounted and a second substrate 32 having a flat plate shape on which the processor C and the like are mounted.
The first substrate 31 is a printed substrate on which the first circuit 1, the first antenna 10, the second circuit 2, and the second antenna 20 are mounted, and a wiring pattern is formed as an electric wiring for electrically connecting these circuits and antennas. The first substrate 31 is formed in a hexagonal flat plate shape in which one side of a rectangle protrudes outward in a mesa shape, for example.
The second substrate 32 is a printed substrate on which the processor C, the memory unit M, and a power supply circuit (not shown) of the module 100 are mounted, and on which electrical wiring is formed. The second substrate 32 is formed in a rectangular flat plate shape. The electric wiring of the second substrate 32 and the electric wiring of the first substrate 31 are electrically connected by a lead or the like. Further, the power supply circuit is driven by the electric power supplied from the door D (vehicle 200).
The first antenna 10 is a pattern antenna formed as a wiring pattern of the first substrate 31 and is formed in a coil shape. The first antenna 10 is wired along the periphery of the first substrate 31.
The first circuit 1 is constituted by an ASIC for performing the first communication and electronic components such as an IC attached to the ASIC. The first circuit 1 is electrically connected to the first antenna 10, inputs and outputs electromagnetic waves via the first antenna 10, and communicates with the terminal S. The first circuit 1 is disposed in an area inside a loop-shaped wiring forming the first antenna 10.
Fig. 3 shows a schematic circuit diagram of the terminal S. Fig. 4 shows a schematic circuit diagram of the first circuit 1 and the first antenna 10.
As shown in fig. 4, the first circuit 1 includes a drive circuit 11 that drives the first antenna 10 to transmit an electromagnetic wave, a restoration unit 12 that restores the electromagnetic wave received by the first antenna 10 to acquire information (for example, ID information), a resistor 13, and capacitors 14 and 15. The drive circuit 11 is electrically connected in series with the capacitor 15, the resistor 13, and the first antenna 10 in this order from one end of the electrode thereof, and the other end of the first antenna 10 is electrically connected to the other electrode of the drive circuit 11. The capacitor 14 is connected to a wiring between the capacitor 15 and the resistor 13 and a wiring on the other end side of the first antenna 10.
The drive circuit 11 transmits an unmodulated signal (applies an ac voltage) that is amplified by resonating in an RLC resonance circuit including a resistor 13, the first antenna 10, and a capacitor 15, and is transmitted from the first antenna 10 as an electromagnetic wave.
When an electromagnetic wave is transmitted from the first antenna 10 and received by the terminal antenna 93 of the terminal S shown in fig. 3 (an example of a power feeding process), energy of the electromagnetic wave is accumulated by resonance of an RLC resonance circuit including the resistor 92, the terminal antenna 93, and the capacitor 94, and the terminal circuit 91 is driven (an example of wireless power feeding). The terminal circuit 91 drives the terminal antenna 93 by the accumulated energy, and transmits the modulated electromagnetic wave including the ID information of itself to the terminal antenna 93. Therefore, when the first communication is performed, the terminal S does not necessarily need power supply from its own battery. Even when the secondary battery is consumed (the battery is dead) and the power supply is not possible, the terminal S can perform the first communication by the energy of the electromagnetic wave transmitted from the first antenna 10.
A signal (voltage) of an electromagnetic wave received by the first antenna 10 shown in fig. 4 is resonated and amplified by an RLC resonant circuit including the resistor 13, the first antenna 10, and the capacitor 14, and is restored by the restoring unit 12.
When the first circuit 1 performs the first communication to acquire the ID information, the processor C transmits the ID information from the first circuit 1 to the ECU. When the ECU acquires the ID information, the ID information is collated with the license ID. If the acquired ID information matches the license ID, the ECU determines that locking/unlocking is possible and issues a locking/unlocking command.
As shown in fig. 1, the second antenna 20 is a pattern antenna formed as a wiring pattern of the first substrate 31, and is formed in a reciprocating rectangular wave shape. The second antenna 20 is disposed in an area inside the loop-shaped wiring forming the first antenna 10 in the first substrate 31.
The second circuit 2 is constituted by an ASIC for performing the second communication and electronic components such as an IC attached to the ASIC. The second circuit 2 is electrically connected to the second antenna 20, inputs and outputs electromagnetic waves via the second antenna 20, and communicates with the terminal S. The second circuit 2 is disposed in an area inside the loop-shaped wiring forming the second antenna 20.
When the second circuit 2 performs the second communication to acquire the ID information, the processor C transmits the ID information from the second circuit 2 to the ECU. When the ECU acquires the ID information, the ID information is collated with the license ID. If the acquired ID information matches the license ID, the ECU stands by in a state in which it can receive a request for locking/unlocking (a state in which pairing of Bluetooth communication is successful). When the second circuit 2 receives information including a request for locking and unlocking based on the result of the subsequent communication of the second circuit 2, the processor C transmits the information including the request for locking and unlocking to the ECU. When the ECU acquires this information, it determines that the locking/unlocking is possible and issues a locking/unlocking command.
As shown in fig. 1 and 5, the housing 4 is formed with a first receiving portion 41 that receives the first board 31, a second receiving portion 42 that receives the second board 32, and a seat portion 45 (an example of a fixed portion) that fixes the housing 4 to the door D (see fig. 2) by a screw or the like. The case 4 is formed of a material (in the present embodiment, a material having a resin as a base material) or the like that does not shield electromagnetic waves.
The first housing portion 41 is a box-shaped plate having a slight thickness, and is a housing container having an internal space for housing the entire first substrate 31. The surface of the first housing portion 41 facing the surface of the first substrate 31, that is, the surface facing the outside of the housing 4 is formed in a planar shape.
The second housing portion 42 is a box-shaped plate having a slight thickness, and is a housing container having an internal space for housing the entire second substrate 32. The surface (an example of the imaginary surface) of the second housing portion 42 parallel to the second substrate 32 is orthogonal to the surface parallel to the first substrate 31, and the surface of the second housing portion 42 parallel to the second substrate 32 houses the second substrate 32 in a state of not intersecting the first substrate 31. That is, the second substrate 32 does not overlap the first substrate 31 when the first substrate 31 is viewed in plan.
One end of the second receiving portion 42 in the longitudinal direction is integrally coupled to one end of the first receiving portion 41. The plate surface of the second housing portion 42 is orthogonal to the plate surface of the first housing portion 41. I.e. the process is repeated. The housing 4 is formed in an L-shape in which the first receiving portion 41 protrudes from one end of the second receiving portion 42 in one direction orthogonal to the extending direction of the second receiving portion 42. Hereinafter, in the module 100 (the housing 4), the side where the first receiving portion 41 is formed in the extending direction of the second receiving portion 42 may be referred to as a front side, and the opposite side may be referred to as a rear side.
The seat portion 45 is a screw seat having a screw hole (not shown) through which a bolt screw, a screw, or the like (hereinafter simply referred to as a screw) is inserted. On the side of second receiving portion 42 from which first receiving portion 41 protrudes when viewed from second receiving portion 42, seat 45 is formed integrally with second receiving portion 42 at a position close to the end of second receiving portion 42 on the side where first receiving portion 41 is joined to second receiving portion 42. The screw hole of the seat 45 is, for example, parallel to the second receiving portion 42 and extends toward the first receiving portion 41. The seat portion 45 is separated from the first housing portion 41 with a gap therebetween.
(locking and unlocking the component fixed)
Fig. 6 is a view of the door D near the door handle N as viewed from the lateral outside of the vehicle 200. The door D includes a vehicle body 60 (an example of a vehicle body) as a metal portion of the door body 6 and a door handle N provided to the door body 6.
The door handle N includes a handle case 61 (an example of an opening/closing operation unit) as a handle for opening/closing the door D by a user, and a support frame 62 thereof. The module 100 is mounted on the inner side of the vehicle 200 viewed from the handle case 61 on the rear R side of the door handle N, and covers the module 100 from the lateral outside of the vehicle 200 through the handle case 61. The handle case 61 is formed of a material (in the present embodiment, a material using a resin as a base material) or the like that does not shield electromagnetic waves. When the user wants to lock and unlock the door D, the user can lock and unlock the door D by covering the terminal S near the rear R side of the door handle N with the first communication being performed. The vicinity of the rear R side of the door handle N is a portion on which a cylinder of a key for unlocking and locking is mounted in a conventional vehicle. By mounting the unit 100 on the rear R side of the door handle N, the locking and unlocking can be performed by an operation close to a certain operation that the user has been familiar with, and therefore, the user can feel a good feeling of use.
Fig. 7 is a view of the door D in the vicinity of the door handle N as viewed from the lateral outside of the vehicle 200, and is a view as viewed from the lateral outside of the vehicle 200 with the door handle N removed. Fig. 8 is a schematic cross-sectional view of the door D in a plan view for explaining an attachment method of the door handle N and the module 100 to the door body 6. As shown in fig. 8, a handle case 61 of the door handle N, a vehicle body 60 of the door body 6 of the door D, and a support frame 62 of the door handle N are arranged from the lateral outer side toward the inner side of the vehicle 200 (see fig. 2). When viewed in the width direction of vehicle 200, handle case 61 is disposed to overlap support frame 62. The width direction of the vehicle 200 is a direction intersecting the front-rear direction and parallel to the ground. Hereinafter, the same direction as the width direction of the vehicle 200 will be simply referred to as the width direction.
As shown in fig. 7 and 8, the vehicle body 60 is formed with a pair of door handle fixing holes 60a penetrating the vehicle body 60. A support frame 62 that rotatably supports a handle case 61 (see fig. 8) is disposed on the inner side (vehicle compartment side) of a vehicle body 60 (see fig. 2). A door handle N is fixed to the door handle fixing hole 60 a.
An insertion hole 62b (an example of a module holding portion) through which the module 100 is inserted from the back side and a fixing hole 62c to which the handle case 61 is attached are formed inside the outer edge of the support frame 62. The fixing holes 62c are formed in a pair (only one fixing hole 62c is shown, and the other fixing hole is not shown), and are arranged so as to overlap the door handle fixing hole 60a when viewed in the width direction.
As shown in fig. 8, the support frame 62 is paired with a mount 62a, and is fixed to the vehicle body 60 by sandwiching the periphery of the door handle fixing hole 62a through the door handle fixing hole 60 a. Thus, the door handle N is mounted (fixed) on the vehicle body 60 in a state where the support frame 62 disposed on the inner side of the vehicle body 60 and the handle case 61 disposed on the outer side of the vehicle body 60 sandwich the vehicle body 60.
The insertion hole 62b holds the module 100 in a state in which the back side of the module 100 faces the inside in the width direction. The module 100 is fitted into and fixedly held by the support frame 62 in a state where the housing 4 is inserted through the insertion hole 62b from the width direction outer side. When the module 100 is fixed and held in this manner, the seat portion 45 integrally formed with the housing 4 is fixed and attached from the inside of the vehicle 60 by a fixing member such as a screw. The inner surface shape of the insertion hole 62b is formed along the outer side shape of the housing 4 so that the housing 4 of the inserted module 100 is tightly fitted. In the present embodiment, the insertion hole 62b has the same shape as a hole for holding a cylinder of a conventional key device.
The insertion hole 62b is disposed at the same position as that of the cylinder holding the conventional key device. The installation height of the insertion hole 62b with respect to the ground surface is the same as the height of the cylinder holding the conventional key device. In fig. 7 and 8, the insertion hole 62b is at the same height as the handle case 61, and the insertion hole 62b is shown to be disposed on the rear R side of the door handle N. The insertion hole 62b may be disposed on the front F side of the door handle N. The insertion hole 62b is disposed to overlap the door handle fixing hole 60a when viewed in the width direction.
Since the handle case 61 is disposed to overlap the support frame 62 when viewed in the width direction, the insertion hole 62b and the assembly 100 inserted through the insertion hole 62b are disposed in the vicinity of a portion where a cylinder of a conventional unlocking/locking key is disposed.
In addition, as shown in fig. 8, a part of the seat portion 45 in the assembly 100 is screw-fixed to the vehicle body 60, so that the assembly 100 is fixed to the door main body 6.
As shown in fig. 7 and 8, in the module 100, the first substrate 31 (first antenna 10) is disposed on the lateral outer side of the door main body 6 with respect to the vehicle 200. The first base plate 31 is disposed on the same plane as the vehicle body 60 or is disposed so as to protrude further outward than the vehicle body 60 in the lateral direction of the vehicle 200. The first substrate 31 is disposed along the surface of the vehicle body 60.
(Lock unlock operation)
When the user wants to lock/unlock the door D while the user is away from the vehicle 200, the user can instruct (transmit information including a request for locking/unlocking) the lock/unlock to the module 100 by the operation of the terminal S or the like as long as the terminal S and the module 100 can perform the second communication. However, when the battery of the terminal S is dead, the terminal S cannot be operated, or the terminal S is positioned on the front surface of the door D, the terminal S covers the vicinity of the end portion of the door handle N on the rear R side and performs the first communication, thereby instructing locking and unlocking of the door D.
As described above, it is possible to provide a lock/unlock module that can select an appropriate communication method from a plurality of communication methods and use the selected communication method.
(other embodiments)
(1) In the above-described embodiment, the case where the first circuit 1, the first antenna 10, the second circuit 2, and the second antenna 20 are mounted on the first substrate 31 of the module 100, and the processor C and the storage unit M are mounted on the second substrate 32 has been described. However, as shown in fig. 9, the first antenna 10 may be mounted on the first substrate 31 of the module 100, and the first circuit 1, the second circuit 2, the second antenna 20, the processor C, and the storage unit M may be mounted on the second substrate 32.
When the first antenna 10 is mounted on the first substrate 31 and the first circuit 1, the second circuit 2, the second antenna 20, the processor C, and the storage unit M are mounted on the second substrate 32, it is preferable that the second antenna 20 and the first substrate 31 do not overlap each other when the first substrate 31 is viewed in a plan view (see fig. 5). With such a non-overlapping configuration, electromagnetic waves for performing the second communication are not shielded by the first substrate 31 or the first antenna 10 mounted on the first substrate 31, and interference between the first communication via the first antenna 10 and the second communication via the second antenna 20 can be avoided, so that appropriate communication can be performed.
(2) In the above-described embodiment, the case where the module 100 is configured to be able to communicate with the terminal S by two communication methods, the short-range wireless communication method and the long-range wireless communication method, has been described. However, the module 100 may be configured to be able to communicate with the terminal S by two different short-range wireless communication methods. In this case, at least one of the communication systems may be a communication system capable of communicating with the terminal S without requiring power supply from its own battery.
(3) In the above-described embodiment, the case where the second substrate 32 does not overlap with the first substrate 31 when the first substrate 31 is viewed in a plan view is described. However, the second substrate 32 may overlap the first substrate 31 in the plan view, and even in this case, the module 100 can communicate with the terminal S.
(4) In the above-described embodiment, the description has been given of the case where the first substrate 31 (first antenna 10) is disposed on the lateral outer side of the door main body 6 with respect to the vehicle 200, and is disposed on the same plane as the vehicle body 60 or is disposed so as to protrude further outward than the vehicle body 60 with respect to the lateral outer side of the vehicle 200, but the first substrate 31 (first antenna 10) may be disposed further inward than the vehicle body 60 with respect to the vehicle 200, and in this case, the module 100 may also be able to communicate with the terminal S.
(5) In the above-described embodiment, the case where the module 100 is mounted on the rear R side of the door handle N on the inner side of the vehicle 200 as viewed from the handle case 61 is described. However, the module 100 may be mounted on the inside of the vehicle 200 when viewed from the handle case 61 on the front F side of the door handle N.
(6) In the above-described embodiment, the case where the module 100 is mounted on the inner side of the vehicle 200 as viewed from the handle case 61 on the rear R side of the door handle N and the lateral outer side of the vehicle 200 is covered with the handle case 61 has been described. However, if the unit 100 is mounted near the door handle N, the user feels comfortable. In this case, the assembly 100 may not be covered by the handle case 61. For example, the module 100 may be mounted at a position below the door handle N in the vertical direction. The module 100 may be mounted on the rear R side of the door handle N and at a position below the door handle N in the vertical direction. The lower part is closer to the hand of the user than the upper part of the door handle N, and the use feeling of the user is good. In this case, the first substrate 31 is preferably disposed on the same plane as the vehicle body 60 or on the laterally inner side of the vehicle body 60 with respect to the vehicle 200. In this case, the module 100 may be accommodated in the support frame 62, but may be fixed to the door main body 6 only by screwing the seat portion 45 to the vehicle body 60, or the like, without being accommodated in the support frame 62.
(7) In the above-described embodiment, the case where the ECU determines the locking/unlocking has been described. However, the component 100 (processor C) may determine whether to lock or unlock.
(8) In the above-described embodiment, the case where the first communication is the NFC communication method and the second communication is Bluetooth is exemplified. However, the first communication and the second communication may be in other communication systems. For example, the first communication may employ other communication methods such as RFID. The second communication may be a communication system such as Wi-Fi or ZigBee (ZigBee or registered trademark), or may be so-called UWB.
(9) In the above-described embodiment, the case where the housing 4 of the module 100 is inserted into the insertion hole 62b and is fitted into and fixed to the support frame 62, and the seat portion 45 of the module 100 is screwed to the vehicle body 60 and fixed to the door main body 6 has been described. However, the assembly 100 may or may not be directly fixed to the door main body 6 as long as it is fixed to at least the support frame 62.
(10) In the above-described embodiment, the case 4 of the module 100 is inserted into the insertion hole 62b and is fitted into and fixed to the support frame 62, but the module 100 may be fixed to the support frame 62 by another method such as screwing or snap-fitting.
(11) In the above-described embodiment, the case where the module 100 is configured to be able to communicate with the terminal S by two communication methods, that is, a short-range wireless communication method (an example of a first communication method) and a long-range wireless communication method (an example of a second communication method), and the module 100 includes the first circuit 1 (an example of a first communication unit) that performs wireless communication with the terminal S by the short-range wireless communication method, the first antenna 10 (an example of a power supply coil) connected to the first circuit 1, the second circuit 2 (an example of a second communication unit) that performs wireless communication with the terminal S by the long-range wireless communication method, the substrate 3 on which the circuit such as the second antenna 20 connected to the second circuit 2 is mounted, and the case 4 in which the substrate 3 is housed has been described. However, as shown in fig. 10, the module 100 may include a substrate 3 on which a first antenna 10 connected to at least the first circuit 1 that performs wireless communication with the terminal S by the short-range wireless communication method is mounted, and a case 4 in which the substrate 3 is housed.
Note that the configurations disclosed in the above embodiments (including other embodiments, the same below) can be combined with those disclosed in other embodiments as appropriate without causing any contradiction, and the embodiments disclosed in the present specification are illustrative, and the embodiments of the present invention are not limited thereto, and can be changed as appropriate within a range not departing from the object of the present invention.
